摘要：A high-sensitivity phase noise measurement scheme using photonic-delay line and digital phase demodulation is proposed, which is free of complicate calibration and amplitude noise by using digital phase demodulation. In the experiment, a phase noise measurement sensitivity as high as-134 dBc/Hz@10 kHz@10 GHz is achieved applying a 2-km single mode fiber as the delay line. Besides, accurate phase noise measurement in a large frequency bandwidth from 2 to 35 GHz is achieved.
